mm TOOL.

Application s July 31.,

following is a specification.

Thisinvention relates to a tool adapted to bend sheet metal tongues as an incident to a tying operation. More particularly it is adapted for use with studdings of the general kind that are disclosed in my appli cation hereto-fore filed December 11, 1919 as Serial No. 343,992 As an object of this invention I have aimed to produce a tool whichmay be used by the unskilled to effect a bending-operation which is uniform in its results the tool having special-characteristics which adapt'it to the particular use herein suggested. I

In the drawing is represented an exemplification of this invention in the manner following:

Figure 1 is a view in perspective of two plaster boards tied to a studding by tongues which are bent with the present tool;

, Figs. 2, 3, andt are side elevations of the tool shown in connection with the stud-- ding, three different stages in the bending operation being illustrated; and I Fig. 5 1s a perspectlve view of per se.

As an example of the use to which the present tool may advantageously be applied, 1 have shown in Fig. l a metal studding A to which plaster boards B are secured. In one wall of the studding are "formed parallel slits 6 with a small opening 7 between them at one end. In this manner there is provided a tongue 8 which is bendable outwardly from the studding, the free end of the tongue being bendable upon itself as at 9. to grip a pin 10 that engages the outer side of the adjacent plaster boards to thereby tie them to the studding. It is with a tool that is specially adapted to effect the double bending of the tongue in this manner that my invention is concerned.

the tool Referrin now to Fi 5 the tool com rises a pair of levers of the first class pivoted to gether as at 12. One endof each lever is formed with a handle portion 18, the two handles being disposed substantially parallel in the manner common to small hand tools. A spring 14 may be arranged be- Specification. of Letters Patent. I A1103 22 1922?,

tween the handles, as shown,fto normally hold them apart the maximum distance.

l-Each lever in the region of its'intersection is appropriately recessed to provide a neck 15, and at its end is formed with a ne tongue tolbe bent. Normally these two remain open under theactlon o 'f the spring is so as to freely receive the tongue but when pressure is applied upon the handles the tongue is firmly clamped between the aws. The outer jaw s further ner jaw to provide a stop which limits the termed, as at vl9, to co-operate with the inmovement of the'handles away from each other.

In the use ofthis tool in connection with a studding such as is shown in Fig. 1, the short outer jaw is inserted in the opening 7 preliminary to positioning the two jaws on opposite sides of the tongue 8. This stage of the operation is illustrated in Fig. 2. The

final position of these jaws with the tongue between them is reached when the end of the tonguelodges at 18 against'the neck ad- I iacent the outer jaw as indicated in Fig. 3. In this position toe end of the inner jaw is disposed just between the lower ends of the two slits 6 in the line of bend where the tongue is to project outwardly from the studding body. Having positioned the tool in this manner, the tongue is bent from the studding to the position of Fig. 3. The pin 10 is now'set in' place upon the tongue next to the end of the outer jaw. The tool is then reversed in its movement to bend the tongue upon itself and around the pin, as

clearly shown in Fig. 4:. During this last tongue, but may be readily" withdrawn therefrom. As a result of the operations just described, the tongue is bent twice, the

first time at the exact line between the lower ends of the two slits 6, and the second time upon itseli? to curl around the pin which engages the plaster boards. The bending operations just described may accordingly be performed expeditiously and uniformly by means of the present tool which is specially constructed for this purpose.

I claim:

1. A tool of the kind described comprising a pair of pivoted levers each formed with a handle end, means for normally holding apart their handle ends, a aw carried by each lever its opposite end, both jaws being co-acting and disposed in a direction which is generally transverse to the medial line between the levers, the inside jaw being extended beyond the other, and a stop between the two jaws to limit the distance of entry of a tongue therebetween, the inside jaw having a length. substantially equal to that of the tongue to be bent, substantially as described.

2. A tool or" the kind described comprising a pair of pivoted levers of the first class having one end of each formed to provide a handle and the other end formed to provide a jaw which is disposed generally in a direction transverse to the medial line he tween the handles, the two jaws being of unequal length, the inside one belng the longer, means between the aws for llmltlng the entry of a tongue therebetween, the inside jaw extending outwardly from said limiting means a distance substantially equal to the length of the tongue to be bent, and spring means tending to hold the aws apart, substantially as described.

A tool of the kind described comprisaws being of unequal length, the inside one.

the longer and substantially the same in length as the tongue to be bent, the length of the outer jaw being that or the tongue portion which is to be bent upon itself, and means between the jaws for determining the extent to which the tongue may be received bet veen them, substantially as de-- scribed.
